Picked up a package of 10 LED bulbs for about $4, ended up getting a few sizes too small, but they barely did still fit.
I got 36mm size bulbs, but I probably needed 41mm. The difference is amazing and they are so much brighter, can't wait to see them in the dark.
Here's a photo of the difference between the 2 brightness in bulbs:
Will add additional pics of how they look in the dome light, and the comparison of sizes
